The mechanical properties of an Mg–Zn–Ca alloy were significantly improved through extrusion deformation. High-density spheroidal Ca₂Mg₆Zn₃ with a diameter ranging from 10 to 50 nm dynamically precipitated during extrusion deformation. The microstructure of the as-extruded alloy was obviously refined compared with that of the as-cast counterpart. A bimodal microstructure consisting of coarsely deformed grains and finely recrystallised grains was obtained through extrusion. Additionally, the as-extruded alloy exhibited a strong basal texture. Consequently, the yield strength increased from 42 MPa of the as-cast alloy to 285 MPa of the as-extruded alloy.

Mg-Zn-Ca 合金的力学性能通过挤压变形得到显着改善。在挤压变形过程中动态析出直径为 10 至 50 nm 的高密度球状 Ca ₂ Mg ₆ Zn ₃。与铸态合金相比，挤压态合金的显微组织明显细化。通过挤压获得由粗变形晶粒和细细再结晶晶粒组成的双峰显微组织。此外，挤压态合金表现出强烈的基底织构。因此，屈服强度从铸态合金的 42 MPa 增加到挤压态合金的 285 MPa。
